Welcome to the Evidence-Based Hair Podcast, hosted by dermatologist and hair loss specialist Dr. Jeff Donovan. In this episode, Dr. Donovan explores a groundbreaking study published in the journal Curious, highlighting the effectiveness of the JAK1 inhibitor, upadacitinib, in treating recalcitrant dissecting cellulitis of the scalp. Dissecting cellulitis, a challenging form of scarring alopecia, often affects males and presents with debilitating symptoms. While traditional treatments like isotretinoin and antibiotics offer relief for some, they aren't always effective. The study discusses a case where upadacitinib brought significant improvement after conventional options were exhausted. Dr. Donovan provides a comprehensive overview of the study, emphasizing the potential of JAK inhibitors as third-line treatments in managing persistent dissecting cellulitis. He also shares insights on the broader implications for future research and treatment strategies. Join Dr. Donovan next week for an analysis of a study on alopecia areata and cardiovascular comorbidities, and don't miss the annual "Top 20 of 2024" event on December 30th.
